Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.

Summary

This study looks at whether lying flat (0 degrees) or with the head raised (30 degrees or more) after a stroke clot removal procedure helps people recover better. About 2240 adults who had a stroke from a large blood vessel blockage will be randomly assigned to one of the two head positions. The goal is to see if a simple change in bed position can reduce disability and improve outcomes.

The number the study aims to enrol. It can still change while the study runs.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age 18 years or older on the date of randomization * Endovascular thrombectomy (EVT) for large vessel occlusion (LVO) in the anterior circulation, according to current guidelines and local standards of clinical care. The definition of LVO may include the intracranial segment of the internal carotid artery (ICA), and/ or the M1 segment (proximal, mid, distal) of the middle cerebral artery (M1-MCA), and/ or the proximal M2 segment of the MCA (M2-MCA) * Capable of giving signed informed consent either independently, or by a legally authorized representative (LAR), or via a deferred consent process approved by the relevant ethics committee, which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol. Exclusion Criteria: * Mechanical ventilatory support for acute medical condition prior to procedure (i.e. required for reasons other than procedure) * Symptomatic congestive heart failure, chronic obstructive pulmonary disease, or any other medical condition that would make either HoB position inappropriate for patient care in the judgement of the investigator. * Any condition, such as but not limited to, agitation/ delirium or severe nausea/ vomiting, that, in the view of the investigator, is expected to significantly impede maintaining the assigned HoB * Any condition with life expectancy of less than 3 months * Inability to randomize within 1 hour from the end of the EVT
